I had a problem a while back where a mechanical relay controlled a motor and it caused emi that caused a bit of havoc on the controller. Changing the mechanical relay for a solid state relay solved the problem.
In another scenario I have the inductive load controlled by a mechanical switch which causes the same problem. Given that the voltage is 220v ac, would it not be possible to connect a suitably large capacitor across the switch like what is done on the controller or is this looking for trouble?
